Kriss USA Defiance Front Flip-Up Black AR-15 Low Profile Steel DAFSBL00

Kriss USA Defiance Front Flip-Up Sight — Low-Profile Steel, Black (Model DAFSBL00 / UPC 810237026519) Round out your optic setup with a rugged, low-profile backup: the Kriss USA Defiance Front Flip-Up Sight (DAFSBL00) is a precision-machined steel front sight engineered to be a reliable iron-sight backup for AR-15 platforms. Designed to work seamlessly with low-profile rear sights and modern red-dot optics, the Defiance front sight provides quick target acquisition, rock-solid zero retention, and the durability to withstand heavy use in tactical, training, and field environments. Built for real-world reliability The Defiance front flip-up sight combines a low silhouette for co-witness compatibility with a robust steel construction that resists deformation and maintains alignment under repeated recoil. When stowed, it stays tucked under your optic footprint to preserve cheek weld and sight picture; when needed, it deploys instantly and locks into place with a positive detent for repeatable accuracy. Kriss USA engineered the Defiance series to meet the demands of professional users and serious enthusiasts who want a dependable mechanical back-up to electronic optics. Key Features & Benefits Model: DAFSBL00 UPC: 810237026519 Construction: Heat-treated steel body for superior strength and longevity compared with polymer alternatives. Finish: Matte black corrosion-resistant coating to reduce glare and blend with black rails/slides. Low-Profile Design: Sits low on the rail when stowed so it won’t obstruct red-dot or holographic optics. Quick-Deploy Flip Mechanism: Spring-assisted or detent-assisted flip up for fast, one-hand deployment under stress. Secure Locking: Positive locking detent holds the sight rigidly in the deployed position to preserve zero. Compatibility: Fits standard Picatinny / MIL-STD-1913 rails — ideal for AR-15, AR-10 and other 1913-rail platforms. Aperture/Blade Options: Precision sight post engineered for clear front-sight acquisition and co-witness setups. Durability: Steel construction resists cracking, deformation, and wear from repeated stow/deploy cycles and rough handling. Low-Weight Profile: Designed to add minimal weight while maximizing rigidity and reliability. Performance & Use Cases The Kriss Defiance front sight is perfect for shooters who primarily use optics but require a fast, robust iron backup in case of optic failure, battery loss, or damage. Common applications include: Optic backup: Low-profile when stowed, clear sight picture when deployed — ideal behind red dots and magnified optics. Tactical / Duty rifles: Durable steel construction meets the needs of patrol, security, and professional users. Competition & Training: Reliable, repeatable aiming reference for drills where optics may be swapped or disabled. Hunting & Field: Rugged enough for rough field use while keeping a compact profile on the rail. Design & Engineering Notes Low obstruction: The sight’s low stowed height maintains cheek weld and minimizes interference with micro-red dots and holographic sights. Positive detent: The deployed detent prevents wobble and keeps the post in the same orientation shot after shot. Precision post: The sight post is cut and centered to deliver a consistent point-of-impact relative to co-witnessed optics when properly zeroed. Serviceable: Simple, user-serviceable components — easy to clean and inspect as part of regular maintenance. Installation & Adjustment (High-Level) Mounting: Install on any standard Picatinny rail segment. Position the sight forward of your optic as required for the desired co-witness (absolute or lower 1/3). Securing: Tighten the sight’s clamp or mounting screw to the rail per the manufacturer torque recommendations—ensure a snug, wobble-free fit. Deploy & Zero: Flip the sight up, align with your front post or optic, and perform a live-fire or bore-sight zero to establish precise point of aim. Maintenance: Periodically check mounting hardware and detent for wear; clean grit from the flip hinge and apply a light film of corrosion inhibitor if operating in harsh environments. For precise torque specs, sight heights, or specialized co-witness setups consult Kriss USA documentation or a qualified armorer. Durability & Care Finish care: Wipe with a dry or lightly oiled cloth after exposure to sweat, salt, or dirt to protect the matte finish. Inspection: Regularly inspect the hinge, detent, and mounting clamp for signs of wear; replace if the locking detent loses tension. Compatibility check: Confirm rail alignment and clearance with your optic’s footprint prior to final torque to avoid interference. Technical Specifications (At-a-Glance) Manufacturer: Kriss USA Model: Defiance Front Flip-Up Sight (DAFSBL00) UPC: 810237026519 Material: Heat-treated steel Finish: Matte black corrosion-resistant coating Mount: Picatinny / MIL-STD-1913 compatible Style: Low-profile flip-up front sight / post Deployment: Spring/detent assisted flip with positive lock Weight: Lightweight for a steel sight (adds minimal mass) Intended Use: Backup iron sight for AR-15, AR-10 and other 1913-rail firearms Frequently Asked Questions (FAQ) Q: Will this sight co-witness with my red dot? A: Yes — when positioned correctly the Defiance front sight is designed to be low enough when stowed to allow lower-1/3 or absolute co-witness with many micro red-dot optics. Always confirm clearance and sight picture on your specific optic before use. Q: Is this more durable than polymer flip sights? A: Yes — constructed from heat-treated steel, the Defiance front sight offers superior resistance to cracking and wear compared with most polymer alternatives. Q: How do I zero it? A: Mount and secure the sight, deploy the sight post, then bore-sight or live-fire adjust to achieve the desired point of impact. Use the rear sight or your optic as the reference during zeroing.
